The third volume of the historical novel series by Simon Scarrow
In the winter of 44 AD, the Roman army captured the city of Camulodunum after a series of bloody battles. While General Plautius, commander of the Second Legion, he's figuring out a course of action for the next campaign, Ship, on which his wife and children are traveling, will be destroyed by the storm. The general's family falls into the thrall of a dark Druid brotherhood demanding the release of their brothers, who have been captured by the Romans. Two volunteers from Plautius' Legion must venture into the heart of enemy territory and attempt to free the prisoners before the druids sacrifice them to their dark gods. The protagonists Macro and Cato must find out where the Druids are holding the General's family. Will they figure out how to save them before the deadline expires?
